  • the acrylic copolymer is generally formed into a powder or granules for use in the PVC foam.
  • the powder may be formed by typical means, such as spray drying, drum drying, freeze drying, vacuum drying, or coagulation by physical or chemical means.

  • the chemical blowing agent can be a solid or fluid.
  • Useful blowing agents include, but are not limited to, azodicarbonamide, azodiisobutyronitile,
  • sulfonylsemicarbazide 4,4-oxybenzene, barium azodicarboxylate, 5-Phenyltetrazole, p-toluenesulfonylsemicarbazide, diisopropyl hydrazodicarboxylate, 4,4'- oxybis (benzenesulfonylhydrazide) , diphenylsulf one-3 ,3 ' -disulfohydrazide, isatoic anhydride, N,N'-dimethyl-N,N'dinitroterephthalamide, citric acid/sodium

  • a nucleating agent is sometimes used to aid in foam formation.
  • the acrylic copolymer and other additives may be added directly to the PVC or CPVC composition, or may be pre-blended into a masterbatch to improve blending and manufacturing control.
  • extruder as used herein is meant a thermoforming device in which a homogeneous mixture of the polymer, blowing agent, and other additives exits as a foam.
  • Useful extruders of the invention include, but are not limited to single and double screw extruders, blow molding devices, and injection molding devices.
  • the process of extrusion and sizing is a continuous process.
  • blow molding and injection molding the process is non-continuous, and results in an article of a part for an article.
  • the PVC, acrylic copolymer, filler and other additives are heated inside the extruder above its melting point in the presence of foaming and nucleating agents.
  • foaming and nucleating agents When a chemical foaming agent is used, the temperature is raised above the decomposition temperature of the foaming agent, generating gas, which is then absorbed by the molten polymer under high pressure.
  • gas or fluid can be injected into the molten polymer. Gasses are excellent plasticizers for polymers.
  • the polymer/gas mixture has sufficient melt strength and viscosity when it exits the die and is exposed to the atmospheric pressure. At this point, the gas dissolved in the polymer comes out of solution and generates gas cells in the polymer. These cells grow until the gas in the polymer is depleted and the polymer is further cooled down, resisting further expansion. The foam expansion ceases once there is a balance between the gas pressure in the bubble and the extensional viscosity of the polymer melt. During this process, the foam is commonly sent through a sizer.
  • the lower Tg acrylic copolymer of the invention allows for the processing of PVC and CPVC foam at lower temperatures and/or faster fusion of PVC foam compounds at similar temperatures.
  • fusion must first occur to ensure adequate melt strength to capture and contain the gas from the chemical or physical blowing agent.
  • the timing of fusion is very important, as one must balance the fusion of the PVC or CPVC compound with the generation of gas from the degradation of the chemical blowing agent.
  • the net effect is a wider processing window for the polymer matrix, allowing a wider variety of equipment and processing conditions to combine for good quality foam products. While increased processing temperatures can shorten fusion time, they also shorten the time to gas evolution from the chemical blowing agent.
  • This invention offers the potential to fuse the PVC or CPVC compound faster at the same processing temperature, which will not materially affect the time to gas evolution from the chemical blowing Agent.
  • the lower Tg of this process aid increases the entanglment of the PVC or CPVC resin, which allows for a better transfer of energy from the extruder to the formulation. This better transfer allows for a quicker fusion time at a given processing temperature. Additionally, the same effect can allow for similar fusion time at a lower processing temperature.
  • the acrylic copolymer of the invention can provide as much as a 10°C cooler processing temperature for similar fusion profile. Cooler operating temperatures allow for quicker downstream cooling, which offer the benefit of potential faster production speeds, or improved product quality/appearance due to less heat history of the polymer. Additionally, it saves on energy costs/unit extruded.
  • the PVC or CPVC foam of the invention has good mechanical stability and load bearing properties.
  • the foamed structure has a density that is at least 3% less than said non-foamed PVC, and more preferably at least 25% less.
  • the density reduction could be 35% less, 50% less and even as high as 100 times less dense than the non-foamed PVC material.
  • Another benefit of maintaining similar fusion while operating at lower temperatures is a decreased heat history of the polymeric foam melt. In many applications, the foam is cooled slowly and the long heat history of the slow cooling can lead to discoloration of the foamed article. The lower processing temperatures, however, aid in shortening the cooling time and thus improving the foamed articles color.
  • the foam cell size is as small as possible.
  • the cell size could be as small as 1 micron.
  • the cell size is in the range of from 10 to 250 microns, more typically in the range of from 50 to 150 microns.
  • An advantage of PVC foamed structures is their higher strength-to-weight ratio.
  • Another advantage of the foamed structure of the invention is an increased impact resistance, increased hysteresis, reduced dielectric constant, and increased compressibility over non-foamed PVC.
  • the foamed structures also provide increased insulation - both thermal and sound insulation to articles made from the foamed structure.
  • the foamed PVC structures of the invention could be used in the same applications as their solid counterparts. They would have the advantage of being lighter, saving shipping costs and making handling easier. Since the structures are lighter, they could find application where light weight is important, for example insulation panels, piping including foamed-core piping, trim pieces, and decking products.
  • a typical PVC foam formulation without blowing agent (see Addendum, Table 1), was blended using a common high-intensity mixer. The formulation was then tested in a torque rheometer, a standard industry tool. The torque rheometer test shows that fusion time of the polymer can be shortened at the same temperature. Repeating the test at lower temperatures shows that equivalent fusion times can be at a lower temperature. Table 2 shows the temperatures tested, while Table 3 shows the fusion times experienced. Further, a pair of match fusion points are shown in Table 4, displaying that processing conditions can be approximately 10°C cooler.
